Dubai can either refer to one of the seven emirates that constitute United Arab Emirates (UAE) in the eastern Arabian Peninsula, or that emirate's main city, sometimes called "Dubai city" to distinguish it from the emirate. From a small fishing village to the frontrunner of world tourism Dubai has come a long way. Revenues from petroleum and natural gas contribute less than 3% of Dubai's US$ 46 billion economy. A majority of the emirate's revenues are from the Jebel Ali free zone authority and, increasingly, from tourism and other service businesses. Dubai has attracted world-wide attention through innovative real estate projects and sports events. However, this increased attention, coinciding with its emergence as a world business hub, has also highlighted human rights issues concerning its largely foreign workforce.
